T W M Patented Aug. 22, 1933 UNITED STATES PATENT oF-Fics 2 Claims.

This invention relates to toilet articles and has special reference to permanent wave apparatus.

More particularly the invention relates to an adapter or connector used for connecting a standard form of the hair curler used in per manent waving to a flexible shaft such as is driven by a motor and to which various hair dressing and massaging devices are adapted to be attached in beauty shops and hair dressing parlors. Ordinarily such flexible shafts may be directly connected to the device to be used but with the hair curlers necessary in permanent waving the curler consists of a rod or mandrel having a head on one end and on this rod is fitted a revoluble winding element which grips a strand or tress of the hair as the element is turned and winds it onto the rod. This winding element is the revoluble element of the device and, because of the rod, the ordinary flexible shaft arrangement for attaching to such things as vibrators cannot be here used. Moreover, after the winding is accomplished a tubular heating element is slipped over the whole device so that any attachment used to connect the winding element with the motor shaft must be removed.

Heretofore all such winding has been done by hand and is a tedious operation and, since a Very considerable number of these devices must be used on a persons head, much time has heretofore been wasted in this operation. Moreover, due to the difficulty of doing this by hand without allowing the rod to slip or tip such turning of the rod sometimes takes place with consequent pulling of the customers hair.

The important objects of the present invention include providing novel means by which the flexible shaft of an electric motor may be connected to the usual form of such devices, to enable such device to be readily placed on and removed from such devices so as not to interfere with the placing of the heater tube on the device, to enable such connection to be made without the use of tools, and to construct the connecting device in a simple manner without complicated arrangements.

With the above and other objects in view as .will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawing and specifically claimed.

In the accompanying drawing like characters of reference indicate like parts of the several views, and: i I 1 Figure 1 is a sideelevation of the device as applied'to a standard form.

Figure 2 is a longitudinal sectionof the invention with the hair curler shown in elevation.

Figure 3 is an enlarged detail section on th line 3-3 of Figure 1.

I In the embodiment of the invention shown in the accompanying drawing there is illustrated ahair curler having a rod'or mandrel 10 provided on its forward end with an enlarged disk like head or cap 11 having a padded face 12 which rests practically against the scalp when the device is in use. On this rod is mounted a winder having a forward portion 13 provided with a hookl l to catch the strand or tress of hair. A rear portion 15 revolubly fits the rod' 10 andis connected to the forward portion by bars 16 arranged on diametrically opposite sides of the rod 10.

It is clearly to be understood that I am not confined to the use of this particular form of curler and that the invention is to be used with any of the standard or commonly used hair curlers, the present form being shown merely as typical of such devices.

The adapter or connector consists of an inner tube 17 adapted to receive the rod 10 and on the forward end of this inner tube is mounted a tubular head 18 shaped to grip the revolving element of the curler. In the present instance there is provided a diametrically disposed pair of notches 19 in this head and these notches fit over the bars 16. It is to be understood that the invention is not confined to this notch arrangement as any form of means may be used for effecting gripping of the revolving curler element by the head. It is quite common, however, for such revolving elements to have some form of flattened finger grip such as is afforded by the bars in the present showing and the notches form a preferable construction in most cases. Practically all flexible shafts, such as are used in hair dressing andv beauty parlors, are provided with a short shaft at the end to-which the apparatus used is connected and this shaft is provided with a key or spline. The rear end of the tube 17 is accordingly adapted to receive the forward end of a flexible shaft and is provided with a keyway 20 for the shaft key. A handle or housing 21 is fitted on the tube 17 and the fit is such that the tube may revolve freely in the handle. A screw 22 extends through the wall of the handle and engages in a circumferential groove 23 formed around the tube 17 so that the handle and tube are held together without interfering with the rotation of the tube 17. A ball catch 24 of the usual construction is provided in the handle to engage the head of theflexihle shaft as is common in all shaft driven devices.

In using the device the hair curler is positioned on the head in the usual manner but, instead of rotating the curler by hand, the connector, which has already been attached to the flexible motor shaft, is clipped over the rod and engages the rotatable element which is thus rapidly rotated. This operation, due to the speed of the shaft, takes but a small fraction of the time consumed in the hand operation and, since there is practically no tendency to tilt or for the rod to 'slip such as occurs in hand winding, all pulling of the hair is avoided.

There has thus been provided a simple and efficient device of thefkind described and for the purpose specified.

It is obvious that minor changes may be made in the form and construction of the invention Without departing from the material spirit thereof. It is not, therefore, desired to confine the invention to the exact form herein shown and described, but it is desired to include all such asproperly come within the scope claimed.

Having thus described the invention, what I is claimed as new, is: 7

1. A connector for connecting a flexible shaft and a hair curler of the type having a rod and a winding element revoluble thereon, said connector consisting of an elongated tube adapted to receive the curler rod and having at its forward ends means for engaging'the winding element to rotate the same, s'aid tube having at its rear end means to receive the driving end of a flexible shaft, and a handle wherein said tube is rotatably mounted, said handle being provided with means for attachment of a flexible shaft head.

2. The combination with a hair curler having a rod forming a mandrel and provided with a scalp engaging head at its forward end, a winding element revolubly and slidably mounted on said rod and having means for engaging a strand of hair; of driving means for the winding element comprising an innertube adapted to fit removably over the rear portion of the rod and having means at its rear end for driving engagement by the rotating element of a flexible shaft, a head on the forward end of said inner tube adapted for removable driving engagement with the winding element of the curler, a tubular handle in which the inner tube is revolubly mounted, and means carried by the handle for detachably connecting the handle to a non-rotatable part of a flexible shaft.
